# INA286AQDRQ1

**Texas Instruments** · Current Sense Amplifiers · SOIC-8

INA286AQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -IN | input | Connection to the negative side of the shunt resistor (analog input). |
| 2 | GND | power_in | Analog ground. |
| 3 | REF2 | input | Reference voltage input, 0 V to V+; see Section 7.4.1 for connection options. |
| 4 | NC | unconnected | Not internally connected; the NC pin should either be left floating or connected to GND. |
| 5 | OUT | output | Analog output voltage. |
| 6 | V+ | power_in | Analog power supply, 2.7 V to 18 V. |
| 7 | REF1 | input | Reference voltage input, 0 V to V+; see Section 7.4.1 for connection options. |
| 8 | +IN | input | Connection to the positive side of the shunt resistor (analog input). |
